Hydrocephalus is a potentially debilitating neurological condition that primarily affects babies under a year of age and has traditionally been treated by inserting a shunt between the brain and the abdomen. A newer endoscopic procedure offers hope of shunt- free treatment that may reduce complications over a child's life, but it is not clear if the endoscopic procedure results in similar intellectual outcome as shunt. Therefore, the investigators propose a randomized trial to compare intellectual outcome and brain structural integrity between these two treatments, to help families make the best treatment decision for their baby.

Research suggests that consuming more fatty fish, fruits, and vegetables could potentially shield the lungs from the negative impacts of air pollution. The research team will look at whether a dietary intervention aimed at increasing intake of these foods can protect the lungs from woodsmoke as the air pollutant and look into how this works.

Addressing brain health and cognitive impairment (CI) in the aging population is important, especially in those undergoing surgery. While certain adverse outcomes are beyond control due to various factors, some may be preventable, such as delirium. It is crucial for patients and their families to be fully aware of the heightened risks associated with CI. By discussing the implications for individuals and their families, patients can make informed decisions about their health. Additionally, patients can be better prepared for their post-operative care and informed about post-operative complications. Education is a practical and viable solution to promote awareness and empower individuals to manage their cognitive health, especially in the context of surgery. Also, it can act as an early intervention. Thus, there is a need to proactively educate older adults about brain health. The objective of the Web-Based Brain Health Education Study is to determine the impact of preoperative education on the knowledge of cognitive health of older surgical patients. Specifically, our study will examine the changes in knowledge scores after patients participate in a web-based education program on promoting brain health during their surgical journey. We hypothesize that a web-based education program will increase patient knowledge and empower them proactively about their brain health during the surgical journey.

The investigators are conducting a pilot (i.e. a small study) in order to find out the effectiveness and safety of medical cannabis in the management of chronic pain. At the end of this 3 month study, investigators will gather information on how easy it is for patients to enroll and complete the entire study. The results of this pilot study will help the study team design a larger randomized controlled trial.

Female participants with type 1 diabetes using oral contraceptives will be asked to wear a continuous glucose monitor for at least three days on two separate occasions (once during the last week of active pills and once during the no pill/placebo pill phase of the menstrual cycle). An exercise session (45 minutes of aerobic exercise at 60% VO2peak on a cycle ergometer) will take place at 5 pm on the second day of glucose monitoring.

This study will assess short and long term outcomes of individuals undergoing minimally invasive surgery of the gastro-esophageal junction (MISGEJ). Patients will respond to questionnaires on an annual basis evaluating quality of life and functionality following MISGEJ. Hospital charts will also be reviewed on an annual basis to assess patient health outcomes.

Obsessive-compulsive disorder (OCD) is a severe and debilitating anxiety disorder afflicting about 2% of the population. It is characterized by the presence of recurrent obsessions and/or compulsions that are time consuming and cause marked distress and/or impairment. Untreated, OCD runs a chronic and deteriorating course. According to the World Health Organization, OCD is among the top 10 leading causes of disability worldwide. Examination of non-medicinal treatments for OCD has focused on two distinct treatments: exposure and response prevention (ERP) and cognitive therapy (CT), often combined into an integrated cognitive-behavioural treatment (CBT). CBT is considered the first line psychological treatment for OCD, with estimates of response rates of between 70-80%. However, there are a significant number of treatment non-responders and the majority of responders are still left with impairing residual symptoms. One area of investigation that has shown potential benefit for general mood and anxiety disorders has been mindfulness-based interventions (MBIs), yet the potential benefits of MBIs in OCD has been largely unexamined, except for several small preliminary studies that show clinical promise. The purpose of this study is to examine the clinical benefits of a standardized MBI treatment for OCD in a large-scale, multi-site randomized controlled trial. The results of this study will directly determine whether Mindfulness can be considered an effective treatment for OCD. If this study can demonstrate that a short-term mindfulness intervention can significantly reduce the suffering associated with OCD, then the findings could easily be translated into routine clinical care in and out of hospital settings. Results of this study will also potentially add to our understanding of the mechanisms that drive OCD symptoms, improve our knowledge of psychological treatment mechanisms, and elucidate how biological factors influence psychological treatment outcomes.

Fluid-unresponsive hypotension needing cardiotropic drug treatment is a serious complication in very preterm neonates with suspected late-onset sepsis (LOS; defined as culture positive or negative bloodstream infection or necrotizing enterocolitis occurring \>48 hours of age). In Canada, \~250 very preterm neonates receive cardiotropic drugs for LOS related fluid-unresponsive hypotension every year; of these \~35-40% die. Unlike for adult patients, there is little evidence to inform practice. While several medications are used by clinicians, the most frequently used medications are Dopamine (DA) and Norepinephrine (NE). However, their relative impact on patient outcomes and safety is not known resulting in significant uncertainty and inter- and intra-unit variability in practice. Conducting large randomized trials in this subpopulation can be operationally challenging and expensive. Comparative effectiveness research (CER), is a feasible alternative which can generate high-quality real-world evidence using real-world data, by comparing the impact of different clinical practices. Aim: To conduct an international CER study, using a pragmatic clinical trial design, in conjunction with the existing infrastructure of the Canadian Neonatal Network to identify the optimal management of hypotension in very preterm neonates with suspected LOS. Objective: To compare the relative effectiveness and safety of pharmacologically equivalent dosages of DA versus NE for primary pharmacotherapy for fluid-unresponsive hypotension in preterm infants born ≤ 32 weeks gestational age with suspected LOS. Hypothesis: Primary treatment with NE will be associated with a lower mortality Methods: This CER project will compare management approach at the unit-level allowing inclusion of all eligible patients admitted during the study period. 16 centers in Canada, 2 centers in Ireland, 1 center in each of Israel, Spain and the UK, and 6 centers in the United States have agreed to standardize their practice. All eligible patients deemed circulatory insufficient will receive fluid therapy (minimum 10-20 cc/kg). If hypotension remains unresolved: Dopamine Units: start at 5mics/kg/min, increase every 16-30 minutes by 5 mics/kg/min to a maximum dose of 15 mics/kg/min or adequate response Norepinephrine Units: start at 0.05 mics/kg/min, increase every 16-30 minutes by 0.05 mics/kg/min to maximum dose of 0.15/mics/kg/min or adequate response

This is a multisite randomized controlled registry-based trial to evaluate the efficacy of an 8-week home-based exergaming intervention as compared to usual care on occupational satisfaction of children and youth (8-18 years old age) with spinal muscular atrophy (SMA).

The objective of this study is to nake a comparison between 11c-acetate and 11c-acetoacetate kidney uptake in chronic kidney failure patients.
